oil filter (2011)

openroad · May 21, 2011

Went to town for an oil filter, used the numbers from the Tech Digest to cross match. Carquest guy said their filters are made by Wix, so I ordered one. Came in a few days later, cardboard box looked really old, opened it up, ......not a Wix filter:

Looks like it's been sitting on the warehouse shelf for a long time.

This is what was on the scoot, can't remember when it was installed:

Nothing wrong with Mann filters, good quality brand.

I was wondering if I should order a couple more?

No way. There are a literally dozens of filters that will cross over to the Commando. For instance, 2000 Ducati 750 or 900 SS and many many more years and models oil filter is perfect for the Norton. I keep an extra KN153 on the shelf not because I am worried about them running out, I just like the way it looks there.

I got a couple of Wix 51352 the other day for my shakedown runs, I think after that I'll be getting the 51032, it has 10 micron rating, the 51352 has 27 micron. Amsoil sells the Wix filters, but I got them at a local auto store for about $10 ea. They looked like they had been in the warehouse for a while, but were clean. I got the filter kit from RGM and it came with a Fram PH2839 which will be changed in about 50 miles. I use Wix in all my cars and farm equipment unless I have it changed at a shop.

Really, same filter with different filtration ratings?

DogT · May 22, 2011

No, 51352 and 51032. Slightly different size too. You can look them up on the Wix site.

Interestingly enough last year when exchanging emails with the tech department of a big producer of motorcycle oils, they indicated that the only real purpose of paper element filters in relation to air cooled MC applications, was to prevent large size particles of debris of the type produced when an engine is badly damaged, from finding its way through the lubrication system.

Apparently the filters simply are not fine enough to stop the type of material that most commonly causes wear, and are no substitute for the regular oil changes that are pretty much essential on all older bikes.

DogT · May 22, 2011

Well, I ran this S for years without an oil filter. After 13K miles, there was hardly anything in the sump trap, but then I'm pretty sure I changed the oil a lot.

I use a modern MANN filter along with Synthetic oil - it certainly keeps the oil better looking for longer than a cheap filter with Straight 40 or 50 like I used in the past. I also thought that most paper element filters were long gone, being replaced with modern man made fibre filter media. I would not worry to much about it being an old filter as long as the rubber seal is not perished, it was most probably manufactured to a better standard than a newer cheap filter that can be easily obtained. Yes there are Ducati filters that will fit, but I would bet they cost a lot more than a equivalent MANN or FRAM filter from a auto outlet.

A little higher? I quess so. Do you get what you pay for? More than likely. Would you want any less insurance for your beloved? NO!
The NAPA is $9.69 and the specs are right-on for the Norton. Over Priced? Not for chrome. Also made by wix.

Here's another for $13.99. Same great specs. Too high a price? Not for that nut on the back. It's awesome!

oil filters may change internally without external evidence.
Any particular part number may not even be internally identical sitting side by each on the shelf.
The engineering and purchasing specs change and so do the insides.
The only true way to know a filter is to dissect it.
Has anyone here had a failure related to a filter manufacturing error?
I have used a few different makes over time, OCD, Filtech, Baldwin, Purolator, Wix on and on.
Not only on motorbikes mind you, had one leaker and it was my fault, double gasketed in a blind hurry.
No real damage other that cleaning up a big puddle on the old man's floor.
The cheapo's didn't let me down nor did the others.
If it makes you feel better then spend the extra.
Peace of mind is like independence in that there is a premium paid for each.
BTW my latest B7292 Baldwins shipped direct to me from Kearney, Nebraska, via Cyprus, there is just no telling what is inside anymore without destructive analysis.

I rode my 72 Combat 5000 miles across the USA in the summer of 72 without an oil filter fitted.
I took the filter off my 73 850 and have run it for the past 38 years without an oil filter.

Never had any motor issues or problems.

Not suggesting to anyone they don't "need" an oil filter. I just felt the placement was poor and subject to
rocks hitting it and multiple additional oil hose leak possibilities. I also felt if I changed the oil every 1500 that I did not need a filter.

Works for me after all these years. And if I had had a filter fitted I would also say it works for me.

Purolator FC 103 or OC 5
Tecafilter Ref OC5
Technocar R12, R72, R434 TJ FB2094
Unipart GFE 201

Why not buy or make a threaded adapter to screw on your filter plate and use a car filter for half the price of a motorcycle filter. There are many talented machinist out there that can do it for you. The UFI guzzi filter works fine too @ $7.00 ea. Been using them for years. Right now with an adapter I use a fram 3614, them same one for my wife's Toyota. With the money you'll save you can change the oil more often...........

I remember the parts guy saying it fit some French cars, which are rare in these parts.

I think it cost me 9 bucks. Not a horrible price for a filter.

I went to pick up a oil filter at the local NAPA. Not in stock I had to wait a day, then they wanted $36 for it. It was identical to the Mann filter in the first post. Left it there.

A few words of warning about aftermarket oil filters: I have my oil filter modified for the larger 3/4-16 thread that lets you use readily available (and cheaper) car filters. One day I was coming off a stop sign and I thought my rear tire had picked up a nail because the rear end started fishtailing. It wasn't a flat tire. What happened was the oil return line from the engine to the filter had blown off its fitting, and was pumping my engine oil all over the rear end of the bike. If I hadn't felt the rear end fishtailing it would have destroyed my engine. Norton uses straight smooth tubes on the oil filter mount with barely enough room for one small hose clamp. Not good! Turns out my new aftermarket oil filter created just enough extra back pressure to blow the oil lines off of the tubes, even though the hose clamps were tight. I didn't want to go back to the stock oil filter, so I modified my filter mount by drilling and tapping, and installing barbed tube fittings. No more problems with blown hoses.
